.GASOLENE-GAS-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 760,296, dated May1'7, 1904.

' Application filed February 7, 1902. Serial No. 93,060. (No model.)

To all whom it may concern.- e

. Be it known that we, CIIARLEs A. ANDERSON and ERICK A. ERICKSON,citizens of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Gaso- 'lene(jrasl\/laking Machines, of which thefolchines for making gas by saturating air with gasolene-Vapor; and oneof its primary objects is to produce a gas of uniform density in whichthe proportions of air and vapor are constantly maintained.

Another important object of the invention is to utilize whateverexpansion may be created in excess of that produced by the predeterminedproportions of air and vapor to automatically admit air for mixturewiththe gas to reduce its density to the degree desired.

A further object is to make the process en: ti rely automatic andutilize the expansion produced by the saturation of the air with thegasolene-vapor to provide the power for operating the machine. e

The invention also has other objects in view, which will appear fully inthe following detailed description, reference being had to theaccompanying drawings, which illustrate one form of machine in which theinvention may be embodied, and referring to which Figure 1 is a verticalsectional view of a complete machine embodying the invention andconnected with a carbureter and gasholder. Fig. 2 is a side elevation,partly in section, showing the arrangement of the piston and displacerand themechanism for operating them. Fig. 3 is an end elevation showingthe automatic gear. Fig. i is a sectional view of the automatic gear,showing the locking and releasing mechanism. Fig. 5 is a similar viewshowing the shifting spring and the tripping-lever. Fig. 6 is a top planView of the automatic gear, partly in section.

In the accompanying drawings similar letters of reference designatecorresponding parts in all of the figures, and referring thereto, Adesignates a receptacle of cylindrical form, preferably, and partlyfilled with liquid, and B is a disk which is arranged to operate like apiston in the upper part of the receptacle. A flexible sleeve-shapeddiaphragm B is fastened at one edge to the lower side of the disk and atits other edge to the receptaele, being clamped between the flanges a;a. The disk is of lessdiameter than the interior diameter of thereceptacle; but the diaphragm B constitutes an air-tight connectionbetween the disk and sides of the receptacle, so that the disk mayoperate freely'within the receptacle like a piston andwith verylittle'friction.

- A displacer-piston G, closed at the top and open at'the bottom, isarranged to move freely up and down in the cylinder A and below thepower-piston '13, the liquid within the cylinder providing an air-tightand almostfrictionless packing therefor. This displacerpiston isactuated by the movement of the power-piston and at much greater speed,owing to intermediate multiplying devices. It therefore operatestodisplace the air in the chamberbetween itself and the power-piston andforce it through the carbureter. As the displacer-piston rises itreceives the gas from the carbureter with initself above the waterlevel,and when it descends it expels and forces the gas through to the gasholder. Therefore the displacer piston operates to force the air to thecarbureter on its upward movement and force the gas to the gas-holder onits downward movement and is actuated by the power-piston, but atgreater speed.

A rod 0 is connected to the displacerand passes through an aperture [1in the powerp'iston B and a packing-gland 5' andis connected atits upperend by alink a to thelever C. The lei e110. is fulcrumed on the pivotpin6? at one endof a forked lever D, which is pivoted at its other end toastationary support (2' on the cylinder A and is connected by links E andE to the piston B, Fig. 1. A red g connects the outer end of lever 0 tearadial arm ,(ir, Fig. 6, rigidlysecured on the shaft F, journaled inbrackets F FQand another rod 7 is connectedj at one end to the pivot-pind and at its other end to the triplever G, which is carried by a sleeve1;, arranged loosely on the shaftF. Aspiral spring it is arranged'on thesleeve 0 and has one end WV fastened to the rigid arm (1}; and its otherend engaged under a lug w on the sleeve for a purpose hereinafterdescribed. A wheel f is rigidly mounted on the end of the shaft F, andtwo pawls it h, Figs. 4:, 5, are supported on the bracket F and arrangedto alternately engage the inner face of the wheel and lock the wheel andshaft, these pawls being released from looking engagement by anextension eon the sleeve 6. An arm f, carrying a weight f, is alsorigidly secured on the shaft F.

A valve-chamber J, Fig. 1, isconnected with the upper part of thecylinder A, and. it contains the air-inlet valve dand outlet-valve andthe regulatingvalve J. The valves 2' and 2 may consist of any suitableform of check-valve; but the regulating-valve J is controlled by theflexible diaphragm J, to which it is connected by means of the stem 1'.This diaphragm is secured at its outer edge between the flange-K and thecover K, and a compression-spring 7c is interposed between the diaphragmand the cover, the tension of which can be regulated by means of thescrew-plug Z2. The valve-chamber J and the carbureter O are connected bya pipe 0, and the carbureter is connected by a pipe 0' to a pipe L,which extends up in the receptacle above the level of the liquid thereinand within the displacer-piston. i

The carbureter may be of any suitable form and is shown to comprise aplate a, from which cotton wicking or other fibrous material u issuspended in the gasolene U, the wicking serving by capillary action todraw the liquid gasolene up into the carbureting space U, through whichthe air admitted from the passage 0 must pass before escaping to theoutlet-passage O. The regulating-valve J is arranged to admit air forreducing excessive density of the gas, and we have shown this valveconnected by a short passage 0 with the gas-passage 0 adjacent to thecarbureter.

'A pipe P is connected with a pipe 0 within the gas-holder R, and theother end of this pipe P connects with a valve-chamber'L, to which thepipes L and O are also connected. Puppet-valves ZZare arranged in thisvalvechamber L and provided with springs 02 n to assist in holding themagainst their seats and having stems p p, carryingcollars m m. Thesevalves are mechanically operated by the shaft F through the medium ofthe levers H H, Fig. 6, rigid on said shaft, whichengage and operate thelevers I I, loosely mounted on the shaft F and having'their outer endsapertured to receive the valve-stems p and p, the lever I being arrangedbeneath the collar on on stem 19 and the lever I being arranged abovethe collar z' on stem p. i

r is a distributing-pipe, and P is a valve in the pipe P, which isadapted to be operated by the gas-holder, a rod sf being connected tothe gas-holder and provided with a collar T, operating on a rods betweenthe collars tand 5. The rod .5 is connected to a lever S, rigid with thevalve P, and it will be readily understood thatthevalve P will beautomatically closed by the gas-holder as the latter fills with gas andopened as the gas-holder empties.

An air-compressing pump W of any suit able kind is connected by a pipew, having a valve o, with the air-chamber X.

The operation of our machine is as follows: The carbureter is firstsupplied with the required amount'of gasolene, and the valve '0 is thenopened and an initial pressure of about two pounds per square inch, forexample, is produced in the chamber X by means of the air-pump. Thevalve '0 is then closed, and the pressure within the receptacle willcause the power-piston to rise and raise the displacerpiston through itsconnections therewith, the. movement of the displacer-piston, however,being about six times as great as that of the power-piston by reason ofthe arrangement .of the levers. The valve Z is held open mechanically atthis time, and the differential movement of the pistons will create acorrespond: ing diflerence of pressure in the chamber X and in thegas-receiving space within the displacer-piston which causes thecheck-valve z" to open and induces a flow of air from the chamber Xthrough the pipe 0 and carbureter and the pipe 0 to thedisplacer-piston. In its passage through the carbureter the air absorbsthe vapor of the gasolene and increases in volume, which supplies thepower to operate the pumping apparatus and the machine. As the airincreases in volume in a the carbureter by absorbing the gasolene-vapor, the space for receiving the gas from the carbureter must be greaterthan the space containing the air which is supplied to the carbureter.In our machine the volume of the air and gas spaces is correctlyproportioned by the operation of the power and displacer pistons. Theincrease in the volume of gas over the volume of air supplied to thecarbureter varies according to the quality of gasolene used, itstemperature, and other conditions, and it has been found that when thecarbureter contains afresh supply ofhighgrade gasolene a greater volumeof vapor is produced and the air will become excessively saturatedtherewith and of greater density than desired. To avoid this result, weprovide for admitting a supply of fresh air direct from the airchamberto mix with the gas, and thus reduce its density. As the volume of airdelivered to the carbureter and the space for receiving the gas from thecarbureter are in a fixed ratio, therefore should the air absorb morevapor than is contemplated by this ratio the pressure of the gas willincrease and 0perate on the diaphragm J to open the valve J. Thispermits a supply of air to enter through the passage 0, and as this airdoes not pass through the carbureter or absorb any vapor it willdecrease the volume of gas and the Iropressure and reduce the surchargedgas to its proper density. It is apparent that when the vapor absorbedby the air is not excessive the valve J will remain seated. In this waywe utilize the pressure of the expansion of the carbureting process inexcess of the fixed ratio between the air delivered to and the gasreceived from the carbureter to reduce the density of the gas andmaintain the ratio. As the displacer-piston moves upward the trip-leveri is raised and the sleeve 6 turned on the shaft to produce a tension inthe shifting spring it,

and when the displacer-piston has approached the power piston so closeas to almost touch it the extension 0 on the sleeve will engage andrelease the pawl 71, from engagement with the wheel and unlock the shaftF. The pressure of the gas confined by the displacer-piston will forcethat piston upward, compressing the air in chamber X and through themedium thereof forcing up the power-piston, and this movement of thepowerwpiston, aided by the shifting spring now at tension, will turn theshaft now unlocked thereby, closing the valve] and raising the weighty",thus utilizing the expansive force of the gas confined by the'displacer-piston to effect the reversal movement of the piston. Duringthis operation the pistons will move upward at a uniform speed until thelug g) on the wheel f engages with the projection Y on the bracket F, atwhich time the valve Z is open and the shaft is locked by the pawl 72engaging the wheel f with the weight in elevated position. The weight ofthe pistons and their associated parts causes the pistons to descend,and the gas collected in the displacer-piston is forced out through thepassage L, the valve Z, and the passages P and 1' into the gas-holder.While the displacer-piston is descending at a rate of speed about sixtimes as great as the power-piston it will create a partial vacuum inchamber X, causing valve z to open and drawing in air from outside themachine. When the displacer-piston has about reached the limit of itsdownward movement, the extension 6 on the sleeve will engage and releasethe pawl ]2. to unlock the shaft, which is thereupon turned back bymeans of the weight and closes the valve Z through the medium of the armH and lever I. At the same time the power-piston is pulled down, therebycompressing the air in chamber X and producing an initial pressuretherein greater than the pressure in the carbureter and sufficient toopen the valve 2'. Just before the weight reaches its lowest positionthe valve Z will be opened through the levers H and 1, therebyestablishing communication between the car bureter and the displacer andenabling the gas to repeat the operation in the manner hereinbeforedescribed.

If the consumption of gas is less than the volume produced, thegas-holder R will rise until the collar T on the rod S engages withmachine to resume operation.

the collar 6 on the rod 3 and raises the lever S to close the valve P,and thereby stop the operation of the machine by shutting off the outletfor the gas. When the gas-holder descends, the collar T will engage thecollar t and shift the lever S to open the valve P, which again enablesthe gas to escape and the It is apparent that the machine will alwaysstop working during that part of the operation in which it delivers thegas .to the gas-holder, and therefore after the valve P is opened andthe machine is once started it will continue to operate automatically aslong as there is a sufiicient quantity of gasolene in the carbureter.

From the foregoing description it will be understood that we utilize theexpansion obtained in the carbureting process to furnish the power foroperating the machine and regulate the mixing of air and vapor, the airbeing delivered to the curbureter and. the gas received therefrom inmeasured quantities and in lixed ratio to each other. Excess expansiondue to the air taking up too much vapor is made use of by us toautomatically introduce air to mix with the gas and reduce its densityto the predetermined degree, so that the machine will operateautomatically to keep the gas at a uniform density at all times.

Our invention consists, broadly, in regulating themixture in thecarbureting process and utilizing the expansion power derived from thisprocess to operate the machine and supply the air and pressure requiredwithout restriction to the particular character of the machine foraccomplishing these results, and we reserve the right to make any andall "changes in the construction of the machine which fall within thespirit and scope of the invention.

Then the supply of gasolene is wholly or about exhausted or when a poorquality of gasolene is used or when it becomes cooled down by excessiveevaporation, the machine will come to rest because of insufficientexpansion, and in this way our machine is perfectly safe and avoids theproduction of an ex plosive mixture.
